Arbors allow you to attach your hub and blades to the shaft of your wind
generator. It is machined on a computer-controlled lathe to exact
tolerances using 304 stainless steel. This will attach to any
motor/generator shaft that is 1/2 inch in diameter.
This arbor will not rust. Arbors made from steel
(with the exception of stainless steel) will rust away fairly quickly.
Not only is this a waste of your money, it is dangerous! Your wind
turbine has to weather hot and cold, dry and wet conditions. Don't
settle for an inferior arbor made from improper materials.
